dovecot - May 2007 - Quota warning not generated

I am testing out the unofficial quota warning patch with Dovecot 1.0.0, 
and no matter what values I use for the storage or messages values, the 
warning script is never executed.

My plugin settings are:

plugin {
   quota = maildir:storage=20480
   quota_warning = storage=80%:messages=10 /usr/local/bin/quota-warning.sh
}

I've tried the following quota_warning lines without any luck:

quota_warning = storage=80% /usr/local/bin/quota-warning.sh
quota_warning = messages=10 /usr/local/bin/quota-warning.sh
quota_warning = storage=80%:messages=10 /usr/local/bin/quota-warning.sh

The quota-warning.sh script is set to 0755 and currently just syslogs a 
warning using logger(1).  Run independently of Dovecot, it works fine.

Here is a sample maildirsize file (if that is at all important) from when 
I tried the messages=10 setting:

10485760S
335322 12
14016 1
58058 1
46529 1
37623 1
55252 1
61901 1
53422 1
56228 1

There are more than 10 messages in the mailbox, but the quota-warning.sh 
script never gets executed.  When using storage=80%, the maildirsize file 
has the correct values (not included in this message), but it never 
executes the script as well.

Does anyone have any ideas?

Thanks,
-Doug

As I wrote the patch, I do. ;-)
The warning is triggered when the free space goes below the specified  
value, not when the used space goes above. Hence, if you have no limit  
on the message count, no warning on the message count will ever be  
executed.

Moreover, if the free space is already below the specified value, no  
warning is triggered. It is only triggered when a message *brings* the  
free space below the specified value.


Hope this helps,
